The AMSAT News Service bulletins are a free, weekly news and information service of AMSAT, The Radio Amateur Satellite Corporation. ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites.
The news feed on https://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it.
Please send any amateur satellite news or reports to: ans-editor [at] amsat.org
You can sign up for free e-mail delivery of the AMSAT News Service Bulletins via the ANS List; to join this list see: https://mailman.amsat.org/postorius/lists/ans.amsat.org/
HB9RG Trophy Competition – March 3 – 16, 2025
The first QSO via amateur satellite took place on March 10, 1965 when HB9RG and DL6EZA successfully completed a QSO via OSCAR III. In celebration of the 60th anniversary of this historic accomplishment, AMSAT-HB is holding a two week long competition.
The goal is to complete DX QSOs via LEO, MEO, or HEO satellites (GEO satellites are not eligible for the competition). The ten furthest QSOs per participant will be factored into the scoring.
More details on the competition can be found at https://www.amsat-hb.org/hb9rg_trophy/hb9rg_trophy_2025_-_distance

Current Active AMSAT Engineering Projects
AMSAT’s GOLF project is targeting a launch NET (no earlier than) 1Q 2026 for GOLF-TEE, a 3U CubeSat carrying a V/u linear transponder, an X band SDR based downlink, and an active attitude determination and control system. The follow-on GOLF-1 is currently targeted for a launch NET 1Q 2027.
AMSAT’s Fox Plus project is also proceeding towards being ready for a launch of a 1U CubeSat (Fox-Plus-A) with a V/u linear transponder. AMSAT’s Fox-Plus-B is also proceeding with the AMSAT XBT as the core transponder technology. AMSAT’s XBT is intended to break down the barrier between linear and FM transponders using modern signal processing and SDR. It will be capable of providing simultaneous multiple channel operation using multiple modes. All” modes will be simultaneously supported from CW through SSB through narrow band FM through PSK31 (BPSK, QPSK and such) and even SSTV. The signal processing portion of the transponder will be reconfigurable in orbit and the initial design is as a traditional U/v (non-inverting) configuration.
AMSAT’s Fox-Plus-B satellite is also expected to fly AMSAT’s PACSAT payload.
Volunteers are always needed to help bring AMSAT’s Engineering projects to fruition, for more information on how to volunteer, visit https://www.amsat.org/volunteer-for-amsat/

Changes to AMSAT TLE Distribution for February 14, 2025
Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.
This week there are no additions or deletions to the AMSAT TLE distribution.

ARISS News
Amateurs and others around the world may listen in on contacts between amateurs operating in schools and allowing students to interact with astronauts and cosmonauts aboard the International Space Station. The downlink frequency on which to listen is 145.800 MHz worldwide.
Scheduled Contacts
Woodward Mill Elementary School, Lawrenceville, Georgia, direct via K4RGK
The ISS callsign is presently scheduled to be NA1SS
The scheduled crewmember is Don Pettit KD5MDT
The ARISS mentor is K4RGK
Contact is go: Thu 2025-02-20 16:37:28 UTC 47 deg
Watch for Livestream at https://www.youtube.com/live/NfxlSEUOg6A and https://live.ariss.org/
Royal Moroccan Air Academy, Marrakech, Morocco, direct via CN8ERA
The ISS callsign is presently scheduled to be OR4ISS
The scheduled crewmember is Don Pettit KD5MDT
The ARISS mentor is IN3GHZ
Contact is go for: Fri 2025-02-21 11:12:20 UTC 72 deg
Many times a school may make a last minute decision to do a Livestream or run into a last minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication. You can always check https://live.ariss.org/ to see if a school is Livestreaming.
As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.
The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down), If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.
Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time.
The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html
The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html

Upcoming Satellite Operations
A growing number of satellite rovers are currently engaged in sharing their grid square activations on https://hams.at. By visiting the website, you gain easy access to comprehensive information about the operators responsible for activating specific grid squares. Additionally, you have the ability to assess the match score between yourself and a particular rover for a given pass, while also being able to identify the upcoming satellite passes that are accessible from your location.
No current operations listed.

AMSAT Ambassador Activities
AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.
AMSAT Ambassador Clint Bradford, K6LCS, says,
“Think a 75-minute presentation on “working the easy satellites” would be appropriate for your club or event? Let me know by emailing me at k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!”
Clint has NEVER given the exact same show twice: EACH of the 150+ presentations so far has been customized/tailored to their audiences.
